Disney Reference Guide- Hercules

Hi all its been awhile but when cleaning out my closet and found something that was given to me by a former disney artiest. It is a complete Reference guide to the movie Hercules and clearly states its not to be seen by anyone but disney artiest and is property of disney. I dont want to post pictures just cause i dont even know if its something that i can have being its disney property. I would ask the artiest him self more about it but he recently passed. im not sayin what artiest it is. Im curious of the rarity of something like its. Not trying to sell it just kinda curious of what something like this has or would go for.
